EPA Certification Requirements of NGVs
• 1994: EPA sets certification requirements for CNG. – OEMs use of ECMs; concern about conversion emissions;
– OEMs began complying to new standard; SVMs given alternative (Memo 1A Option 3).
– Dozens of “kit manufacturers” leave market (“good”; quality/reliability was a mess)
• April 2002: Option 3 phased out – SVMs must certify; very costly, technically difficult , requires expertise and
$$$ equipment; further differentiated the quality engineered retrofit systems from “kits”
• March 2011: EPA revised aftermarket certification rules – Relaxed rules apply primarily to vehicles “outside useful life” although less
burdensome data submittals are available for vehicles that are “intermediate age” (IUL) defined as current year minus 2; e.g. 2011MY vehicles or older may now apply for IUL listing. Both OUL and IUL still require EPA review of data/technical documentation

Dual Fuel Technologies:
Re-emerging Opportunity • Dual fuel technology is making a comeback, primarily
being marketed to “Intermediate Use (IUL)” and “Out of Useful Life (OUL)” HD engine applications; one company has “new” COC. Could see this option in trucks offered by OEMs
– Varying amounts of diesel is displaced by natural gas during duty cycle
• 3/11 - EPA established a lower cost “approval” process that reduced cost and data burden thus making this dual fuel retrofit system option economically attractive to legacy fleets
• “Approval” process requires technical paper, supporting documentation, field data
• Took 6-8 months to see first “EPA listing.” Presently, ~100 engine families have been approved but more are added each month
– E.g., EcoDual, APG, Clean Air Power, Peake Energy , NGV Motori
